From 34023cd12b5cca3aafb08972defa9f4671c168ce Mon Sep 17 00:00:00 2001 From: H Hartley Sweeten Date: Fri, 27 Apr 2012 16:13:37 -0700 Subject: [PATCH] staging: comedi: refactor pcl816 driver to remove forward declarations Move the module_init/module_exit routines and the associated struct comedi_driver and other variables to the end of the source. This is more typical of how other drivers are written and removes the need for the forward declarations.
